Flaps - SFCC 1 and SFCC 2 Show PCU Valveblock Fault Message

TASK 27-51-00-810-851-A
Flaps - SFCC 1 and SFCC 2 Show PCU Valveblock Fault Message

1. Possible Causes

flaps control lever is out of detent

2. Job Set-up Information
A. Referenced Information

REFERENCE	DESIGNATION
AMM 27-51-00-740-002	BITE Test of the Slat and Flap Control Computers (Flap System)

3. Fault Confirmation
Subtask 27-51-00-710-077-A

A. Test
(1) At the ECAM Control Panel, push the STS P/BSW to show the status page on the lower ECAM DU:

if a FLAPS status message is not shown, there is no flaps fault
if a FLAPS status message is shown, do the fault isolation procedure given in Para. 4.

4. Fault Isolation
Subtask 27-51-00-810-102-A

A. Procedure
(1) Make sure that the flaps control lever is in the correct detent and reset it if necessary:

if the FLAPS status message has gone, there is no fault
if the FLAPS status message stays, do the next step.

NOTE: When the flaps control lever is out of detent , SFCC1 and SFCC2 will find that the lever position and the flap position (signal from the Valveblock PPU) disagree. The FLP 1 (2) PCU VALVEBLOCK 23CV (24CV) message will then be given by each SFCC and the ECAM message FLAPS FAULT will be shown. This flight control configuration error can be cleared by a reset of the flaps control lever.

(2) Do a BITE test of the SFCC1 and SFCC2 flaps system AMM 27-51-00-740-002:

if the test gives a fault message, do the trouble shooting procedure related to this message.
